Bug description:
  [Impact]

  Black screenshots on certain mobile chipsets.

  [Test Case]

  Take a screenshot on affected mobile product.

  [Regression Potential]

  Low, only affects the specified chipsets. Already in use on Ubuntu
  phone and tablet products.

  --

  It seems the screenshots get black on Mali T720 too (frieza) and thus
  the bgra should blacklist should be further extended (from bug
  #1557915 / turbo).

  GL_VENDOR = ARM
  GL_RENDERER = Mali-T720
  GL_VERSION = OpenGL ES 3.1
